OVS-DPDK is now live in various Telco clouds, and this is just the beginning of the roll-out! This presentation will not showcase the latest and greatest of what can be done in a lab. Instead, we will review actual performances on realistic configurations, and provide guidance on OVS-DPDK dimensioning: how many cores, memory, queues, revalidators and dispatcher/emulator thread, etc. We will also review impact of features like stateful firewalling (conntrack), live-migration, LACP bonding and hashing, multicast traffic, cross NUMA traffic on the OVS-DPDK datapath and what is their domain of utilization in NFV: we will measure the distance between expectations/hopes and reality.

Finally, we will review the new features that will improve OVS-DPDK usability in production and for SDN/upper-layers developers: automatic rx queue re-balancing, MTU negotiation, VSPerf characterization with realistic traffic profile and realistic workloads.
